| Abstract: | "A DNA fragment encoding the precursor peptide for alpha mating pheromone was isolated from the S. naganishii genome based on the amino acid sequence of the mature pheromone. The precursor peptide contains three copies of the pheromone. Hydrophobicity analysis of the precursor peptide revealed an N-terminal signal sequence for translocation into the lumen of the endoplasmic reticulum and several signals for a series of secretion-related processes. However, upstream regulatory sequences necessary for expression of the S. cerevisiae alpha mating pheromone gene were not found, suggesting the divergence of systems that regulate alpha mating pheromone gene expression in S. naganishii and S. cerevisiae. Hybridization of a probe corresponding to the S. naganishii alpha mating pheromone nucleotide sequence to S. naganishii chromosomal DNA revealed a single gene located on either chromosome VI or VII. The S. naganishii alpha mating pheromone sequence has been deposited in the DDBJ/EMBL/GenBank data library under Accession No. AB086431" |
